[0017] The specific embodiments of this utility model will be further described below with reference to the accompanying drawings.

[0018] like Figure 1-5As shown, a positioning aid includes a reclining chair 1. Support components are respectively provided on both sides of the reclining chair 1. Each support component includes a main board 2, a connecting plate 3, a secondary plate 4, a support member, a support groove 5 on the support member, and three sets of adjustment units. The main board 2 is connected to the connecting plate 3, the connecting plate 3 to the secondary plate 4, and the secondary plate 4 to the support member via adjustment units. A fixing rod 6 is provided at one end of the main board 2, the connecting plate 3, and the secondary plate 4. Each adjustment unit includes an adjustment disc 7 rotatably connected to the fixing rod 6. A limit disc 8 is provided on the fixing rod 6 and located on one side of the adjustment disc 7. The outer surface of one side of the disc 7 is evenly provided with slots, the outer surface of one side of the limiting disc 8 is evenly provided with protrusions, the adjusting disc 7 and the limiting disc 8 are both provided with grooves on one side, the fixing rod 6 is fitted with a spring 9, the spring 9 is located inside the two grooves, the fixing rod 6 is threadedly connected with a nut 10, the connecting plate 3, the sub-plate 4 and one end of the support are all connected to the adjusting disc 7, the bottom of the recliner 1 is provided with an installation groove, the inside of the installation groove is rotatably connected with a two-way lead screw 11, the main plate 2 in the two support components is threadedly connected to the two-way lead screw 11 respectively, and one end of the two-way lead screw 11 is provided with a handwheel 12.

[0019] The recliner 1 is existing technology and has the functions of height adjustment, backrest adjustment and forward and backward movement.

[0020] The fixing rod 6 is provided with an external thread section, and the screw cap 10 is threadedly connected to the fixing rod 6 through the external thread section on the fixing rod 6.

[0021] The rotation between the main board 2 and the connecting board 3, the rotation between the connecting board 3 and the sub-board 4, and the rotation between the sub-board 4 and the support are all the same. Here, we will only describe in detail the rotation between the connecting board 3 and the sub-board 4.

[0022] The main board 2, connecting board 3, sub-board 4, support component, and fixing rod 6 are all made of metal, such as aluminum alloy, iron, or steel, to ensure that the support groove 5 can bear the weight of the patient's thigh and minimize bending deformation. At the same time, the adjusting plate 7 and the fixing rod 6 can be connected by bearings. The adjusting plate 7 can only rotate on the fixing rod 6 and cannot move along the fixing rod 6. Meanwhile, the inner surface of the limiting plate 8 is provided with a slider, and the fixing rod 6 has a guide groove. The limiting plate 8 can move along the fixing rod 6 through the cooperation of the slider and the guide groove, and the limiting plate 8 will not rotate on the fixing rod 6.

[0023] When controlling the rotation of the sub-plate 4, the position of the connecting plate 3 remains unchanged. Then, rotate the nut 10 to increase the distance between the nut 10 and the connecting plate 3. When the distance between the nut 10 and the connecting plate 3 increases, the length of the spring 9 located in the adjusting plate 7 and the limiting plate 8 will be restored. Therefore, it will push the limiting plate 8 to move away from the adjusting plate 7, so that the protrusion on the limiting plate 8 will disengage from the slot on the adjusting plate 7. At this time, the adjusting plate 7 can be rotated by the sub-plate 4. After the sub-plate 4 rotates to a certain angle, hold the sub-plate 4 by hand to keep it in the predetermined position. Then rotate the nut 10 to push the limiting plate 8 towards the adjusting plate 7 and make the protrusion on the limiting plate 8 enter the slot on the adjusting plate 7. At the same time, the spring 9 located between the adjusting plate 7 and the limiting plate 8 is compressed. When the nut 10 can no longer rotate, the connection between the limiting plate 8 and the adjusting plate 7 is completed, thereby realizing the adjustment of the angle of the sub-plate 4.

[0024] Furthermore, the rotation of the handwheel 12 can drive the rotation of the bidirectional lead screw 11. Through the threaded connection between the bidirectional lead screw 11 and the main board 2, the two main boards 2 can be moved closer or further apart, thereby adjusting the distance between the two support slots 5.

[0025] By using three sets of adjustment units and controlling the distance between the two support slots 5, the position of the support slots 5 can be adjusted more precisely to accommodate a wider range of people and improve patient comfort during use.

[0026] Furthermore, the support includes a top block 13 and a bottom block 14. The top block 13 is fixedly connected to the support groove 5, and the bottom block 14 is fixedly connected to the adjusting plate 7. A column 15 is provided on the upper surface of the bottom block 14, and the bottom block 14 is rotatably connected to the top block 13 through the column 15. Hanging rods 16 are provided on the outer surfaces of both the top block 13 and the bottom block 14. The two hanging rods 16 are connected by a tension spring 17. A bearing groove is provided on the lower surface of the top block 13, and a bearing is installed inside the bearing groove. The column 15 is fixedly connected inside the bearing. The support groove 5 can rotate on the bottom block 14 so that the support groove 5 can better fit the patient's thigh. At the same time, the tension spring 17 can keep the support groove 5 in its initial position to prevent the support groove 5 from shaking and affecting the placement of the patient's leg when the patient has not placed their thigh into the support groove 5. The tension spring 17 can also give the support groove 5 the ability to reset, so as to prevent the patient's thigh from moving too much.

[0027] Furthermore, a limit block 18 is provided on the upper surface of the bottom block 14 to limit the swing amplitude of the support groove 5, so as to ensure that the patient can maintain a proper posture.

[0028] Furthermore, a memory foam padding layer is provided on the upper surface of the support groove 5 to improve patient comfort during use.

[0029] Furthermore, a stop 19 is provided at one end of the fixing rod 6 to prevent the cap 10 from coming off the fixing rod 6.

[0030] In the description of this utility model, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "linking" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.
